Silver foil for Oddy tests

I am seeking a source for silver metal to be used for Oddy testing.
Following the British Museum protocol, it must be 99.5% pure,
unalloyed silver, with a thickness of 0.1mm.  It is the latter
specification which I have been unable to meet after diligently
scouring the supply catalogues.
